To all whom it may concern: holder without the sponge, the sponge-clamp- Be it known that I, SIMEON C. LAWLOR, a ing frames being shown in their normallycitizen of the United States, residing at Duclosed positions. luth, in the county of St. Louis and State of Like numerals of reference mark the same Minnesota, have invented certain new and parts wherever they occur in more than one 55 useful Improvements in Machines for Washfigure of the drawings. ing Windows; and I do hereby declare the fol- Referring to the drawings by numerals, lowing to be a full, clear, and exact descripindicates a hollow vertical standard, which tion of the invention, such as will enable othin the actual operation of the device stands lo ers skilled in the art to which it appertains to outside of the window-frame.

Fig. 2 is a vertical section 24 indicatesasleeve mounted upon the tube through the same on a plane at right angles 22 and secured in position by set-screw 25 or 85 to the plane of Fig. 1 and parallel with the other suitable means. This sleeve carries a Window-pane, as indicated by the broken line frame consisting of two uprights 26, in which 2 2 of Fig. l. Fig. 3 is a transverse section are journaled two rollers 27. A tube 28, through the vertical standard and the sliding passed between the uprights 26 of the sleeve 4o block carrying the window-cleaning sponge or frame, is adapted to be fixed between the 9o or brush. Fig.4is a fragmentary detail per'- opposite faces of the sides of the windowspective view of the vertical standard and frames by means of springs 29 within said the brush-carrying slidable block.

Fig. 6 is an enlarged detail vided with suitable heads 33, held normally inside elevation of a sponge-holder to be subin contact with the sides of the window-frame stituted forthe brush when desired, the sponge and pressed into rigid contact therewith by being shown clamped in the holder. Fig. 7 means of nuts 34 on said screws bearing 5o is a detail view in elevation of the spongeagainst the outer ends of the tube 28. Some Ioo of these features are similar to like parts shown and claimed by me in my application for patent of even date herewith, Serial No. 21,699.

The vertical standard 10.is of peculiar construction, being of horseshoe shape in crosssection with a dat partition 35 connecting the two sides, leaving an undercut or dovetail longitudinal groove 36 outside of said partition or side 35. to fit in said groove and slide freely therein. A cord 37 is secured to the bottom of the block 15 and passes down ward-under the pnlley 23 in the coupling 2O and inward to within easy reach of the operator standing inside the room. Any suitable form of handle, as at 38, may be secured to the tube 22 for con venience in operating the device.

secured to the stem, while the sponge 17 is removably secured between spring clampingframes 40 of elliptical shape, which are normally held closed together, as shown in Fig. 7.

In the operation of the tube 22, carrying with it the Vertical standard 10 and the brush or sponge clamp movable horizontally on the fixed tube 28, the rollers 27 of the carriage permit of easy movement thereof without cramping, whereby the sponge or brush can be moved laterally across the window-pane, so as to be in position to be vertically reciprocated over all parts of the surface of the panes by means of the cord 37 and spring l2. The inward drawing of the cord draws the sliding brush-carrying block 15 downward, extending the spring 12, and the recoil of the spring when the coil is released moves the brushcarrying block l5 upward.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a window-cleaner, a hollow vertical standard horseshoe-shaped in cross-section and provided with a partition connecting its two sides at a short distance from the edges thereof forming a dovetail vertical groove, in combination with adovetail block slidably fitted in said groove, a window-washing device carried by said block, and means for recipro- The block 15 is dovetailed The brush i 39 or body of the brush 18 is permanently eating the block in said groove, substantially 5o as described.

2. In a window-cleaner, a hollow vertical standard horseshoe-shaped in cross-section and provided with a partition connecting its two sides at a short distance from the edges thereof forming a dovetail vertical groove, in combination with a dovetail block slidably fitted in said groove, a window-washing device carried by said block, a pulley journaled in the upper end of the vertical standard, a coupling adjustably secured near the lower end of the standard, a pulley jcurnaled in said coupling, a spring secured in the lower end of the standard, a cord secured to the upper end of the spring passing over the upper pulley and secured to the .dovetail block, and a cord secured to the dovetail block and passed downward under the pulley on the coupling, substantially as described.

3. In a window-washer, the combination with a tube, adapted to be secured between vthe inner faces of the sides of the windowframe, a horizontal tube at right angles to the fixed tube and carrying a window-washing device, a collar adjustably fixed upon the horizontal tube, uprights secured upon said collar and embracing the fixed tube, and two rollers journaled in said uprights and bearing at different points on the upperface of the fixed tube, substantially as described.

l1. In a window-washer, the combination of a vertical hollow standard formed of a piece bent and drawn nearly together at its edges, a partition near its front edges for holding the piece thus together and foriningan interior inclosed vertical passage-way and an eX- terior vertical dovetailed groove along the said standard, a slidable dovetailed block fitted in said groove, means for interchangeably securing a brush :or sponge clamp to said block, and means for reciprocating the block in the groove, substantially as described.

In testimony wherecf I hereunto affix my signature in presence of two witnesses.
